Evaluate the partial integral given two integrans

The video tutorial explains how to find a shaded area by subtracting a smaller area from a larger one. It introduces the problem, provides given values, and discusses the concept of subtracting areas. The instructor uses integrals to mathematically represent the subtraction and performs calculations to arrive at the solution, concluding with a final answer.

Explain how the areas are combined to find the final result.

What is the final calculated value after all operations?
